On Using This Catalog

has to have its own collective number. The Lilt of the Reel was at first a separate
piano piece but was published (Moscow, 1930) as the first of Two Pieces for piano,
no. 463/1. Later HC made three distinct arrangements of it (for varying ensembles)
numbered here chronologically as 463/la, 463/lb, and 463/lc. In the last its ar-
rangement is the fourth of 4 Irish Legends, so for that particular use it becomes
no. 605/4. If this numbering system seems unbearably tedious and complex (Nicolas
Slonimsky, for one, is apt to throw a madman's wisp at its perpetrator), we can
only blame HC and his passion for making different sets.

Entry headings. Headings regularly comprise only two elements: title (including
subtitle, if any; HC did not often use them) and brief designation of the performing
forces (e.g., for piano; for mixed chorus a cappella). Two more elements appear
when appropriate: a dagger () preceding the title, meaning that no copy of a listed
work has been located for description in this catalog; and a date if one is in HC's
caption or on a title-page. Elements of headings not in brackets are direct quota-
tions from HC; those in brackets are usually based on more indirect information
from him or are expansions or abbreviations of his words. Many fragments and even
a few larger works have had to be identified with invented titles-in brackets, of
course, and lightface type.

Some of these "fragments" are fairly long and seemingly complete in themselves;
others, the more numerous, may be less than 16 measures. They have been given
separate entry numbers when they seem to represent some sort of entity more than
just a few scribbled measures, and especially when they obviously constitute the
beginning or ending of a piece. Fragments that represent sketches for recognizable
works are reported under M (see "M" section below) in the entries for those works.
The presence of unidentifiable fragments sometimes scribbled by HC on empty space
on the score of a regular work is merely noted under C (see "C" section below) in
the entry for the listed work.

Tempo indications. Tempo mark or marks, with metronome marks when used by
HC, movement titles if any, and page numbers of sections or movements. Warning
I: HC in later life tended toward long and frequently repetitious patterns of tempo
marks. On occasion these patterns have been abbreviated, especially when past a
first repetition or when only a few measures are affected. Warning II: In his earlier
years HC's marks often reflect his poor spelling: "senate," "non troppe," and "ex-
pressivo" are common. His spelling has been followed as accurately as possible with
only an occasional use of sic.

Tempo marks and paginations in the headings usually are taken from the latest
manuscript source. When there is a published edition, that is generally the source
